Specification of Letters Patent.

Patented Jan. 16, 1906.

Application filed October 5, 1904. Renewed June 15 1905. Serial No. 265,435-

To all whom it may concern:

Be it known that I, JOHN H. SHEPHERD, a citizen of the United States, residing at Huron, in the county of Erie and State of Ohio, have invented certain new and useful Improvements in Window-Sashes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to Window-sashes; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is a front view of a window provided with sashes and guides according to this invention, portions of the frame being broken away to show the guides.

Fig. 2 is a cross-section through the frame,

taken on the line a: as in Fig 1. Fig. 3 is a cross-section through the sill, taken on the line y y in Fig. 1. Fig. 4 is a cross-section through the meeting-rails of the sashes, taken on the line 2 z in Fig. 1.

The window-frame is provided with sides A and a top portion A.

B is the windowsill, and I) is the stool or subsill at the front side of the window inside the room.

O is the lower sliding sash of the window, in which the pane of glass is secured, and D is the upper sliding sash. The meeting-rails of these sashes are preferably provided with interlocking plates 0 and d, as shown in Fig. 4:, so as to make them practically air-tight. The plate d, secured to the upper sash, is angle-shaped in cross-section, so that it can overlap the straight plate 0 of the lower sash.

The sides A of the frame are each provided with a single vertical groove F, and f represents metallic guides secured in the said grooves. These guides are channel-shaped in crosssection and their side flanges 9 have extension-flanges g,which project from their tops and which are bent around parallel the side flanges g, thereby forming two parallel guide grooves h. The upper and lower sashes of the window have flat guide-plates H secured to them in any approved manner,

and these plates are slidable in the guidegrooves h of the metallic guides. The metallic guides and the guide-plates are formed of any approved thin sheet metal which will not rust easily. The upper sash is preferably provided with a plate I-I, similar to the plate H, and the top portion A of the window-frame is provided with a grooved guide similar to the guide f, and so that the top part of the window may be substantially air-tight when the sashes are closed.

The lower window-sash O is provided with an angle-shaped groove 11 in its lower edge.

I is an angle-shaped strip of spring metal provided with a vertical flange 7' upon one side. This vertical flange j issecured to the vertical edge of the stool or subsill b, and the angle-shaped strip is normally supported clear of the sill B. When the lower sash is pushed down, its groove i engages with the angle-shaped strip and presses it into contact with the sill B, thereby forming a substantially air-tight and weather-tight joint.

K represents the ordinary check-rails of the frame, which are secured to its side portions A and which are taken off when it is desired to remove the sashes. The guideplates H and the window-sashes are'placed in position and the plates are then secured to the sashes. The channel-shaped middle portions of the guides form springs, and the guides are sprung into their grooves, so that the guide-plates Hare in close contact with the flanges.

What I claim is 1. The combination, with a window-frame having a single vertical groove in each of its side portions, of channel-shaped guides provided with extension side flanges which form two parallel guide-grooves, said guides being secured in the said vertical grooves, slidable window-sashes, and flat guide-plates secured to the said sashes and engaging with the said guide-grooves.

2. The combination, with a window-frame having grooves in its side and top portions, of guides formed of spring sheet metal and secured in the said grooves, said guides being channel shaped in crosssection and provided with extension side flanges which form guide-grooves, slidable window-sashes, and flat guide-plates secured to the said sashes and engaging with the said guide-grooves.

In testimony whereof I have afliXed my signature in the presence of two witnesses.
